During the first month of class I really worked hard with my students to teach the scientific method, inductive, and deductive reasoning. About 1/3 just don't get it and that has really bothered me. I was wondering what to do to help them when I discovered this morning while talking to a colleague (we both get to school about 90 minutes early each day) that all my students have been taught to think in terms of Claim, Evidence, Reasoning! All that is is looking at the scientific method and deductive reasoning from the other side of the process. Whereas the premise+premise=conclusion and phenomenon-->hypothesis-->experiment-->theory steps take the scientist from virgin observation of nature through to a published journal article, the CER process gives the science student a system for evaluating the published work of scientists, including movies I might show in class and their own textbook! So that is what we started doing today. MUCH FUN!!! I hope this helps me reach the 1/3 who never quite understood my lessons on Aristotle deducing the sphericity of the earth.
An over-arching theme in the science curriculum my school is developing is the question: "What is the energy doing?" So, when I was thinking about the water-cycle unit I thought, "Hmm... the sun is driving this but I don't want to waste all the time involved in marching my students outside and setting up a lab in the outdoors to use the sun's radiation. What can I do?" I was talking to a colleague about this and he suggested using hot plates. So, I went online to see if anyone else had ever done this and found this video that shows how to desalinate water with stuff you have in your own kitchen. After watching the video decided to adapt this guys system to simulate the water cycle. The bonus is that each student will be able to drink the water he will distill. Instead of using metal pans, like in the video, I am going to have my students use 1L cans (the cafeteria is setting them aside for me.). The students will build their own desalination pl...
